GEMENTING APPARATUS.

Application filed June 26, 1820.

To all whom it may concern:

Be it known that 1, Joint W. Coscnovn, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Cementing Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to apparatus for the application of cement. Itis especially adapted for thus coatingportions of shoes,

' as the bottom and foxing areas, preparatory to laying the soles. Work of this character is done by experienced hand operators at a speed and with an accuracy that renders unpromising the successful employment for this purpose of machines at all complicated or difiicult to maintain, or those which are slow to operate.

With such conditions in view, an object of the present invention is to provide a simple apparatus by which the work may be operated upon rapidly and with uniform results. For this purpose, I employ a brush having fibers radiating about an axis, the ends of which fibers furnish an applying surface inclined longitudinally of the axis to correspond generally to the form of the surface to be coated, the arrangement being such that the applying face substantially cor-' responds to the transverse contour of that area of a shoe upper to which the foxing strip is to be applied. With this brush is associated a gage member having its edge adjacent to the ends of the fibers at the extremity of th brush and arranged for contact with the surface to be cemented. With such an organization, a simple movement of the work past the brush properly supplied with cement applies the desired coating. The operation may further be simplified by associating with the foxing-cementing brush, or other applying member, a bottom-cementing member having an upwardly extending surface, here shown as approximately plane, by which th coating of the shoe bottom is effected simultaneously with that of the foxing area. This last-mentioned brush may also serve as a bottom rest to position the work with relation to the toning-cementing brush.

Serial No. 391,983.

Another object of the invention is to arrange for the maintenance of the apparatus in good operating condition and'so that it shall act advantageously for work having the areas to be coated difierently related. In accomplishing this, the inclined brush is preferably arranged to have its applying surface fixed in different positions about its axis. By this expedient, a fresh applying surface may be presented when the fibers become worn. The companion brush, which is best arranged with its applying surface substantially at right angles to the axis of the inclined brush, is fixed for adjustment longitudinally of said axis. This adjustment may be resorted to when the bottomcementing brush becomes worn, and also adapts the apparatus for cementing different heights of foxing areas.

It is an additional object of the invention to supply the cementeffectively to the applying means. This I prefer to do positively and in controllable quantities. To this end, the applying member has a cementdelivering passage, and to this passage cement is supplied through an intermediate conduit. In the conduit is a member movable both to close it to cutoff the supply to a plurality of applying members, as those acting upon the foxing area and upon the shoe bottom, and to exert pressure to force a portion of the cement through the delivering passage.

Hereinafter other objects will be developed, reference being had to the accompanying drawing, in which Fig. 1 is a perspective view of one embodiment of my improved cementing apparatus;

Fig. 2 is a central vertical, longitudinal section therethrough; and

Fig. 3 is a vertical sectional detail through another form of the apparatus.

Upon a suitable frame 10 is mounted a cement container 12, from which the contents may flow by gravity through a conduit or passage, shown as provided in the container and frame. This conduit, below the container, is first vertical at 14, and from this vertical portion it extends horizontally at 16, opening through the side of the frame. The flow may be controlled in the conduit by a valve 18 arranged for rotation to open and close the passage, and having an actuating lever at the side of the apparatus. About the opening of the portion 16 through the frame is arranged a circular recess concentric to the openings. Seated in the recess is an applying member A, here shown as a brush having a cylindrical body 22 fitting the recess at its inner end, froniwhich body radiate bristles or like flexible fibrous members 24-. The applying surface 27 of the brush at the ends of the fi-i'bers is preferably frusto-conical, the inclination being shown as approximatelythe form of the surface to be coated. lVhen a foxing area of the upper of a shoe is to be cemented by its travel longitudinally along the brush, this inclinationmay be between the rather flat transverse contour of such area at the 'shank portion and the more nearly vertical is a boss 80 lying in an axial opening 32 at the center of the brush and alined with the portion 16 of the cement conduit. The re taining screw 26 is threaded through an arm 8 1 fixed vertically on a bracket 36 overhanging the brush. As herein illustrated, the li bers of the brush radiateabout its entire pcriphery, and this allows it to be rotated through 360- degrees to present fresh portions at the working points when other portions become worn. This, however, is not essential, and obviously the brush may be made of some less circumferential dimension. The periphery of the disk 28 is inclined at 38 to a sharp edge, which lies in proximity to the extremities of the brush fihers at the outer or smaller end. The relation of the disk is such that as the work is passed beneath the brush, the reduced edge win come in contact with it, furnishmg a gage to determine the line of the edge of the cemented area, and tending, by its positionbetween the brush and theportion of the work which is to remain uncoated, to prevent the flow of cement outwardly over the latter. Surrounding the inner extremityof the body of the brush and'bearing against the adjacent wall of the frame is a disk 37, which acts as a barrier to the flow of cement in this direction. Passing through the body of the brush from the opening 82 to points between the fibers are passages 40 for the delivery of cement from the conduit to the applying surface. These passages, as shown, are formed about the entire body, but, since only the lower portion of the brush is nsed'at any particular time, to prevent flooding of the upper unused section plugs l2 are inserted in the openings of this idle portion. hen the brush is rotated to bring a fresh applying section into position, the plugs are removed from the corresponding openings and inserted in those which are carried to the inactive position.

I prefer to deliver cement from the con t-ainer to the applying surface under the influence of a positive feeding force and in definite quantities. For this purpose, a rearward horizontal extension 44 of the portion 16 of the cement conduit contains a plungervalve 4:6, to the outer end of which is articulated a bell-crank lever 48 fulcrumed upon the frame. Pivoted to the opposite arm of the bell-crank is a rod' 50 joined to a treadle, which does not appear in the drawing. At the forward end of the plunger is an upwardy inclined surface 52, forming a reduced edge movable across the conduit portion 14. Normally, the lever is held back against an adjustable stop-screw 53, the plunger at this time being at the right of the conduit portion 14, as Viewed in Fig. 2 of the drawings, to open said conduit and permit the portion 16 and connected passages to fill with cement from the container. hen the operator depresses the treadle, the plunger moves across this portion 14, the reduced edge cutting the cement and de creasing the tendency to force it back toward the container; and then, astheclosure of the upper part of the conduit is completed, exerting pressure upon the charge of cement contained in the horizontal portion 16, and forcing it through the brush passages 40 and between the fibers to the applying surface. Th'is operation may be repeated as frequently as is necessary to maintain upon the applying surface the desired quantity of cement.

Simultaneously with the coating of the foxing area of shoe, the bottom may also be cemented. To accomplish this, there is mounted below and adjacent to the inner edge of the applying member A a member B having a rectangular body 54 and projecting fibrous material 56. These constitute a brush, which preferably has a substantially plane applying surface 58, shown as lying approximately at right angles to the axis of the member A. The brush B is carried upon a base 60, from the rear of which a horizontal spindle 62 projects into a socket 64k in the frame, in which it is secured by a set-screw 66 threaded into the frame. The brush may be adjusted by loosening the set-screw and moving said brush either forwardly or rearwardly beneath the brush A to compensate for the shortening of the fibers 56 by wear, or to provide for cementing to difi'erent heights by the brush A. The latter function may be fulfilled because the brush B serves as a bottom rest,

iii

sides of a horizontal axis and near the center of the brush B. These both limit the movement of the work across the brush A by their contact, and also determine the depth to which said work may be forced into the bristles of the brush B, so that this will act most effectively in the application of cement.

As illustrated in Fig. 2, cement is delivered to the brush B under the control of the valve 46. To provide for this, the base 60 is formed with a compartment 70, serving as a receptacle from which cement may fiow through passages 72 formed in the body 54. between the bristles, and generally corresponding in relation and function to the passages tO of the brush A. The top of the compartment is open at 74 and about this opening the brush base fits closely against a horizontal wall 76 of the frame, preventing the leakage of cement at this point. To this opening 74; cement is delivered from the conduit portion 16 by a downward vertical extension 78. This supplies cement to the compartment 70 when the valve 46 is open, and receives pressure upon the closure of said valve to force the cement through the brush passages 72. The opening 74 is enough wider horizontally than the portion 78 of the conduit to enable the latter to deliver cement to the former in all adjusted positions of the brush B.

In using the apparatus for cementing the foxing areas and bottoms of lasted shoes,

one of which is illustrated at S, the brush B is so adjusted in a horizontal direction,

tance between the vertical lines through the ends of the pins 68 and the gage-edge of the disk 28 will substantially equal the height of the foxing area upon the particular work to be operated on. The operator actuates the valve 46 by the treadle to deliver charges of cement from the container through the conduit and delivery passages of both brushes to their applying Surfaces, and then holding ashoe in his hands and pressing it against the ends of the fibers 56, as limited by the pins 68, turns it rapidly beneath and forces it against the brush A until the entire circumference of the foxing area has received cement from the brush A and the bottom has been coated by the brush B. It should be noted that this lastment-ioned brush is of such height vertically that it does not operate across the entire width of the shoe bottom; but itsvertical dimension is sufficient to carr it below the tion to the work and in longitudinalaxis of the shoe, so that in the rotation of the work the entire surface is coated. The operatlons upon successive pieces of work are continued in the same manner, it only being necessary occasionally to replenish the cement in the container and to adjust the brushes A and B to maintain the applying surfaces in correct relaproper condition for applying the cement.

If desired, the means for separately supplying cement from the conduit to the brush B maybe omitted. As appears in Fig. 3,

the body of this brush is mounted upon a.

solid base 80 guided at the upper edge for adjustment, as in the form of apparatus just described against an overhanging frame wall. By the capacity of the conduit or by the frequency with which the cement is sup plied through the operation of the valve 46, an excess over the requirements of the brush A is delivered thereto, and this flows down over the applying surface of the brush B to deliver its charge. The appara.

tus otherwise may be generally the same as that already described.
